Question

x^3+64=0

Answer 1

x=4

Answer 2

honestly i don't know what its called ill type the answer choices

Answer 3

ok

Answer 4

-4, -2+2i(square root)3 and -2-2i(square root)3
-4, 2+2i(square root)3 and 2-2i(square root)3
-4, 2+i(square root)3 and 2-i(square root)3
-4, 2+2(square root)3 and 2-2(square root)3

Answer 5

@TheOcean are you sure about that?
\[x^3+64 = 0\]\[(4)^3 + 64 = 0\]\[64+64=0\]

Answer 6

i would still say tht X=4. like @tgawade said

Answer 7

Come on, it doesn't satisfy the original equation!

Answer 8

thats not what its asking me to do
-4, -2+2i(square root)3 and -2-2i(square root)3
-4, 2+2i(square root)3 and 2-2i(square root)3
-4, 2+i(square root)3 and 2-i(square root)3
-4, 2+2(square root)3 and 2-2(square root)3
these are the answer choices

Answer 9

\[x^3+64 = 0\]\[x^3 +64 - 64 = 0-64\]\[x^3 = -64\]

Answer 10

there are two additional roots to find...

The complex roots will be symmetrically located in the complex plane. They will all have magnitude = 4. If you plot the answer choices, you should be able to figure it out even if you don't understand the math.
